We had several new server with Server 2008 R2 that where identically installed.
On non of this systems we where able to push out the scom agent.
A look at the push log file on the management server (gateways in our case) showed the error message 8000FFFF and something about: registering a firewall rule failed.
Strange, the firewall was disabled on all systems. So, we had a look at the rules on one of the servers and saw a rule called “MOM Agent Installer Service”.
Deleting this rule started to make the push work like a charme.
Digging into the closed monitors on the SCOM, we saw, that the first push failed with the message:
“A system update is in progress”.
So, because of the windows update reboot while the first push was tried, the agent wasn’t installed, but the firewall rule not deleted successfully.
Conclusion:
If push fails with error 80070102 and 8000FFFF in the log, have a look at the firewall on the system, even it is disabled.
